Product Profile of Optical Emission Spectrometer
PBI-Dansensor offers Optical Emission Spectrometer. PBI-Dansensor manufactures gas analysers, gas mixers, gas flow control, etc. The Optical Emission Spectrometer, PDA-7000 series features high sensitivity analysis of nitrogen in steel. Due to the important effects of nitrogen on the mechanical properties of steel, the rapid measurement of nitrogen during the manufacturing process is highly desirable. This Optical Emission Spectrometer has been developed to replace gas analyzers for in-furnace analysis. It achieves a lower detectable limit of 5ppm and the machine reduces sampling operations and shortens analysis times. Additionally, it eliminates sample defects and enhances yields through its ability to control nitrogen in cast iron.
Other key features of this PDA-7000 series Optical Emission Spectrometer:
- Sensitive Analysis of Trace Elements in Steel: The establishment of manufacturing technologies for high-purity iron demands process control at lower trace levels of elements including C, P and S. The PDA meets these needs by permitting quick and easy ppm-level analysis by time resolution PDA photometry.
- Elimination of Contamination Effects: The PDA-7000 Optical Emission Spectrometer effectively eliminates effects from the analysis of aluminium alloys when high purity aluminium is analyzed for example.
- New Spark Stand enhances Stability: The structure and materials of the conventional spark stand have been upgraded to considerably enhance analysis accuracy for high-concentration elements. It accepts large sample plates, offers greater ease of handling and enhances durability.
- Electrode cleaning extends electrode life approx 10 times
- New Chassis Case Design offers good environmental resistance
- Extremely Simple Operation
The PDA-7000 comprises the following parts:
- Excitation unit: The spark stands between the sample and the counter electrode. Emission spectra of the elements in the sample are introduced into the monochromator unit.
- Monochromator unit: splits the light into emission spectral lines. A sensor converts this light into electric currents.
- Photometry unit: measure the generated photocurrents
- Data processing unit: analyzers and processes the measured data
The Optical Emission Spectrometer covers a wide analysis range from trace levels to high concentrations of metals, including steel, aluminium, magnesium, and copper, lead, tin, nickel, etc. It is used for process-control analysis and for raw materials delivery and product dispatch inspections in the metals refining and processing industries.
- Ferrous applications: steel and cast iron
- Non-ferrous applications: aluminium ingot and rolling industries and other metals
- Machinery, automobile and ship-building applications
